Digital transformation is pushing mission-critical storage
environments to the limit, with users expecting data to be accessible
from anywhere, at any time, and on any device. Faced with exponential
data growth, the network must evolve to enable businesses to thrive in
this new era. To meet these dynamic and growing business demands,
organizations need to deploy infrastructure that can deliver greater
consistency, predictability, and performance. Legacy infrastructures,
however, were not designed to support the performance requirements of
evolving workloads and flash-based storage technology. In fact, an
aging network will impede the performance of an all-flash data center.

A new approach to storage networking is needed to enable databases,
virtual servers, desktops, and critical applications, and to unlock
the full capabilities of flash. By treating the network as a
strategic part of a storage environment, organizations can maximize
their productivity and efficiency as they rapidly scale their
environments.

Dashboards: Provide integrated, at-a-glance views that
display an overall storage area network (SAN) health view, along with
details on out-of-range conditions, to help administrators easily
identify trends and quickly pinpoint issues occurring on a switch or
in a fabric.

Flow Monitor: Delivers comprehensive visibility into
flows within the fabric, including the ability to automatically learn
flows and nondisruptively monitor flow performance. Administrators
can monitor all flows from a specific host to multiple targets/logical
unit numbers (LUNs), from multiple hosts to a specific target/LUN, or
across a specific inter-switch link (ISL) or inter-facility link
(IFL). Additionally, they can perform LUN-level monitoring of
specific frame types to identify resource contention or congestion
that is impacting application performance.

Flow Learning: Enables administrators to
nondisruptively discover all flows that go to or come from a specific
host port or a storage port, or traverse ISLs and IFLs or Fibre
Channel over IP (FCIP) tunnels to monitor fabric-wide application
performance. In addition, administrators can discover top and bottom
bandwidth-consuming devices and manage capacity planning.

Flow Generator: Includes a built-in traffic generator
for pretesting and validating the data center infrastructure for
robustness (including route verification and integrity of optics,
cables, ports, back-end connections and ISLs) before deploying
applications.

Flow Mirroring: Enables administrators to
nondisruptively create copies of specific application and data flows
or frame types that can be captured for in-depth analysis.

Evolving critical workloads and higher density virtualization are
continuing to demand greater, more predictable performance. SAN256B-6
director features industry-leading Gen 6 Fibre Channel that increases
performance for demanding workloads across 32 Gbps line-speed links
and up to 16 Tbps of chassis bandwidth to address next-generation I/O
and bandwidth-intensive applications. In addition, the SAN256B-6
director increases scalability with double the throughput for
high-density virtual machine deployments and larger fabrics. This
enables organizations to support more storage devices and meet bandwidth
requirements using the same number of Fibre Channel links.

SAN256B-6 director delivers outstanding chassis, slot-to-slot, and
port performance and bandwidth. In addition, local switching
capabilities ensure that data traffic within the same port group does
not consume slot bandwidth, maximizing the number of line-rate ports
while reducing latency.

Organizations need to adapt to continuous data growth and
seamlessly scale out their storage environments. UltraScale chassis
connectivity leverages optical ICLs to deliver 128 Gbps bandwidth
through a quad small form-factor pluggable (QSFP) link. These links
can support distances of up to two kilometers and connect up to 12
directors, enabling flatter, faster, and simpler fabrics that increase
consolidation while reducing network complexity and costs.

UltraScale ICLs enable scalable core-edge and active-active mesh
chassis topologies. These high-density chassis topologies can reduce
inter-switch cabling by up to 75% and free up to 25% of ports for
servers and storage. This maximizes overall port density within the
smallest amount of rack space while freeing up front-facing device
ports for server and storage connectivity.

With a 32 Gbps Extension Blade, SAN256B-6 director provides
integrated metro and global connectivity with a purpose-built data
center extension solution for Fibre Channel and IP storage
environments. This solution delivers unprecedented performance,
strong security, continuous availability, and simplified management to
handle the unrelenting transfer of data between data centers and
maintain SLAs. Native 10 Gbps Fibre Channel connections are also
available on the 48-port blade and include in-flight compression, as
well as optional support for 10 Gbps Fibre Channel over dense
wavelength division multiplexing (DWDM) and dark fiber.

SAN256B-6 director can scale up to four 32 Gbps Extension Blades
per chassis. Each 32 Gbps Extension Blade provides sixteen 32 Gbps
Fibre Channel/IBM FICON ports, sixteen 1/10-GbE ports, and two 40-GbE
ports to deliver the high bandwidth, port density, and throughput
required for maximum application performance over wide area network
(WAN) connections, and to address the most demanding disaster recovery
requirements.

Extending Fabric Vision technology between data centers provides
unprecedented insight and visibility across the storage network. With
its powerful, built-in monitoring, management, and diagnostic tools,
Fabric Vision technology enables organizations to minimize the impact
of disruptions and outages for nonstop business operations.
Consolidating Fibre Channel/FICON flows and IP storage flows into a
single tunnel contributes significantly to operational excellence. By
using custom, browser-accessible dashboards for combined Fibre Channel
and IP storage, storage administrators have a centralized management
tool to monitor the health and performance of their networks.

IBM Fabric Vision technology

Fabric Vision technology with IO Insight, an extension of b-type
Gen 6 Fibre Channel, provides unprecedented insight and visibility
across the storage network with powerful built-in monitoring,
management, and diagnostic tools that deliver the following benefits:

To realize the full benefits of flash, organizations must
transition their high-performance, latency-sensitive workloads to
flash-based storage with NVMe. The simplicity and efficiency of NVMe
enables significant performance gains for flash storage. Moreover,
NVMe over fabrics enables users to achieve faster application response
times and harness the performance of hundreds of solid-state drives
for better scalability across virtual data centers with flash.

Organizations can also seamlessly integrate b-type Gen 6 Fibre
Channel networks with next-generation NVMe flash storage over fabrics.
The efficiency of Fibre Channel-NVMe, combined with the high
performance and low latency of Gen 6 Fibre Channel, enables
administrators to accelerate IOPS to deliver the performance,
application response time, and scalability needed for next-generation
data centers. When looking for investment protection, SAN256B-6
director offers three generations of backward-compatibility support
for connectivity to 4, 8, and 16 Gbps Fibre Channel products.

Outstanding mainframe technology innovation and
leadership

SAN256B-6 director delivers seamless FICON connectivity for
mainframe storage environments. It complements IBM z Systems by
offering a fast, reliable, and scalable FICON infrastructure, along
with innovative features. The SAN256B-6 director is built on
mainframe leadership that includes designing the FICON standard and
authoring many FICON patents.
